ABSTRACT:
A weapon is provided with means to buffer the recoil which is produced when the weapon is fired. The buffer includes a fluidic device having a first and a second chamber. During recoil, a compressive force is applied to the fluid in the first chamber and flow from the first chamber to the second chamber is restricted by a fluidic diode in relationship to the pressure differential between the first and second chamber. On counter recoil, the fluid flows from the second chamber to the first chamber in an essentially unrestricted manner. The level of flow restriction by the fluidic diode is greater at high pressure differentials than at low pressure differentials.
